Мне предоставил коллегу веб-сервис, который я протестировал, создав быстрый проект .net 3.5. служба предоставляет простой метод, который возвращает DataTable, и все прекрасно работает.
Тем не менее, рабочий проект - .net 1.1, и я получаю сообщение об ошибке во время выполнения в строке, которая создает объект веб-службы:
The XML element '' from namespace 'web/InternetData' is already present in the current scope. Use XML attributes to specify another XML name or namespace for the element.

Моя первая мысль - создать отдельный проект 2.0, который создает дамп данных для повторного использования проектом 1.1, но это кажется ненужным шагом.
